The most important message in the stupidest location:
What is the point of waiting for 10 merges to show us this?
- The surviving person has been merged several times before. Use extra care when determining that these 2 people are the same person.
It tells me that you don't care about the first 10 merges but from then on they are important? Or maybe you are in total denial that your database truly has that many duplicate individuals.
I think you should display this message every time or never.
I would prefer every time in red bold with an additional note that says "some people may appear on the surface to be the same, but after further research might be determined to be two different individuals. To continue is to risk not only damaging your own family, but someone else's as well. "
